Background:During the Renaissance, Nicolaus Copernicus proposed a heliocentric model of the solar system. His work was defended by Galileo Galilei and expanded upon by Johannes Kepler. Kepler was the first to devise a system that correctly described the details of the motion of the planets around the Sun. However, Kepler did not succeed in formulating a theory behind the laws he wrote down. It was Isaac Newton, with his invention of celestial dynamics and his law of gravitation, who finally explained the motions of the planets. Newton also developed the reflecting telescope.Improvements in the size and quality of the telescope led to further discoveries. The English astronomer John Flamsteed catalogued over 3000 stars. More extensive star catalogues were produced by Nicolas Louis de Lacaille. The astronomer William Herschel made a detailed catalog of nebulosity and clusters, and in 1781 discovered the planet Uranus, the first new planet found. The distance to a star was announced in 1838 when the parallax of 61 Cygni was measured by Friedrich Bessel.During the 18–19th centuries, the study of the three-body problem by Leonhard Euler, Alexis Claude Clairaut, and Jean le Rond dAlembert led to more accurate predictions about the motions of the Moon and planets. This work was further refined by Joseph-Louis Lagrange and Pierre Simon Laplace, allowing the masses of the planets and moons to be estimated from their perturbations.Significant advances in astronomy came about with the introduction of new technology, including the spectroscope and photography. Joseph von Fraunhofer discovered about 600 bands in the spectrum of the Sun in 1814–15, which, in 1859, Gustav Kirchhoff ascribed to the presence of different elements. Stars were proven to be similar to the Earths own Sun, but with a wide range of temperatures, masses, and sizes.
Hall, William HenryHall was responsible for a significant publication in the middle of the 18th century The new royal encyclopedia; or, complete modern universal dictionary of arts and sciences on a new and improved plan . containing a digest and display of the whole theory and practice of the liberal and mechanical arts comprising a general repository of ancient and modern literature . including all the material information that is contained in Chamber s Cyclopedia, the Encyclopædia Britannica, and the French Encyclopædie . first published in 1788 going into many re-issues over the next 50 years.The three volume set contained 153 copper-plate prints and maps, including some folding maps. Contained many brief encyclopedic entries in alphabetical orders plus longer, mainly illustrated, sections (systems or treatises) on a variety of subjects: Aerology; Aerostation (hot air balloons); Agriculture; Algebra; Amphibiology; Anatomy; Annuities; Architecture; Arithmetic; Astronomy (includes plates of telescopes); Book-Keeping; Botany; Brewing; Chronology; Chymistry; Comparative Anatomy; Concology; Dialling; Distillation; Drawing; Earth; Earthquakes; Electricity; Entomology; Farriery; Fencing; Fluxions; Fortification; Gardening; Geography (this section includes six folding maps); Geometry; Globes; Grammar; Heraldry; Hydrostatics and Hydraulics (one plate included a diving bell); Icthyology; Knighthood; Logic; Mammalia (included a plate showing whales); Mechanics; Medicine; Mensuration and Gauging; Miscroscopic Apparatus (microscopes); Midwifery; Military Affairs; Music; Natural History; Naval Affairs; Navigation (includes a folding map showing Cooks voyages); Optics; Oratory; Ornithology; Peerage; Perspective; Pneumatics; Projectiles; Steam Engines; Surgery; Surveying; Trigonometry; Vermeology; Volcanos; and War. Hard to find a complete set, as many have been broken up for their handsome copper plate engravings and maps.
